At just 6.8mm, the Pilot V Board Master S offers a great size and grip for school children. With its quick-drying ink and convenient eraser on the cap, it's the perfect tool for learning. With four vivid and vibrant colors, it can bring ideas to life. Pilot even goes the extra mile- their Begreen V Board Master S pen uses recycled plastic, resulting in a -69%** reduction in carbon dioxide emissions compared to using 3 new pens. With just a small gesture, you can make a big difference in our fight against climate change!
